• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky nang x hoi. hieu va cam xuc xa hanh kem ((cau treo) or (((cau tren) OR (ca tren))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang x hoi. hieu va cam xuc xa hanh kem ((cau treo) OR (((cau tren) OR (ca tren)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang x hoi. hieu va cam xuc xa hanh kem ((cau treo) or (((cau tren) OR (ca tren))))".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang x hoi. hieu va cam xuc xa hanh kem ((cau treo) or (((cau tren) OR (ca tren))))*.
